ISKRIT·Geo demo
By agreement
The work of a whole department: roles, history and modules linked together.
- Analyses are tied to the water and soil samples of the site
- The aggressiveness conclusion is assembled for the whole site
- Concrete requirements go into the report with the sections
Questions
What is assessed?
Aggressiveness to concrete and to reinforcement in reinforced concrete, per the SP 28.13330 indicators.
Are concrete grade and exposure conditions needed?
Yes, the degree depends on the water permeability grade and service conditions.
